Move default action from after switch to within

Move from this type of constructions:

switch (val) {
case 1:
	something;
	break;
}
default-action;

into following:

switch (val) {
case 1:
	something;
	break;
default:
	default-action;
	break
}

for cases where the switch statement is not expected to contain a full
set of enum values and as such, does not lose value from not having the
default target.

This makes the intent of default behavior clearer for static analyzers like
gcc with -Wswitch-default.
